Coming from Firefox I really liked when you could right click on an element and hit Q key to open up Inspector with the element highlighted.
On Windows it was always visible, hence the (Q):

On Macs it wasn't, but it worked up until when Firefox recently decided to change their context menu behavior from a custom one to a native one. If you would like to try it out you can open up about:config and set widget.macos.native-context-menus value to false in Firefox.
It would be really great if Orion could have this feature with an ability to customize the shortcut key, but a predefined one (like Q in Firefox) would also work.
